With pump intake connected to inlet strainer and supply
tank or through hull fitting and operation switch off, open
outlet valve, then turn pump switch on. Water will begin
to flow, when water is free of air turn valve off. When
valve is shut off pump will stop. Should pump fail to
stop, turn switch off and see the trouble shooting guide.
As a circulation pump, always run full flow with no
restriction. Use 3.5 GPM pump for tanks up to 30
gallons, and use 5.0 GPM pump for tanks up to 50
gallons. Divert excess water, but do not restrict flow.
For portable use we recommend the pump be mounted
on a base (i.e. 3/4” x 8” x 10” board or plywood), add a
length of cable with alligator clips for battery
connection.
